Metal detectors are interesting electronic devices that you can use to find buried treasures, whether you are trekking across a field or strolling along the beach.
They are widely used by treasure hunters and archaeologists to locate valuable items such as coins, jewelry, metallic accessories, and other numerous artifacts buried under the ground.
If you have ever dreamed of being a treasure hunter, you should invest in a quality metal detector. Not only can you use it to locate precious metals, but also find keys and pennies if you happen to drop them in the grass.
After conducting thorough research, we have compiled a list of the best metal detectors available in the market. They all have unique benefits and serves different purposes, so choose as per your needs.
9. Garrett ACE 300
Best for: Beginners and intermediate level hunters
Garrett ACE 300 has all the depth and technology you need to make your treasure hunting adventures and rewarding. It has five detection modes: Zero-Disc, Jewelry, Coin, Relic, and Custom modes.
The zero-pick mode activates the sensor to detect all types of metals and identify good objects that are hidden near trash ones. In custom mode, you can add or eliminate certain types of materials, which increases the chances of finding your target object.
- Adjustable frequency
- Has five detection modes
- Target depth Indicator
- Control of how much iron discrimination to apply
- Little unstable over saltwater, as it doesn’t offer ground balance
The detector features a digital target ID (numerical scale from 0 to 99) that shows the conductivity of the target metal. Higher values indicate large jewelry, gold nuggets, silver, and copper. Lower values represent small jewelry, steel, and iron. All in all, this scale can help you precisely determine what kind of object is buried beneath the surface.
It’s a great deal for $250. Along with the detector, you will receive a submersible search coil and a headphone.

1. Fisher F75
Best for: beach hunting, gold hunting, coin shooting, and gold prospecting
Fisher F75 combines advanced features and technology with an easy-to-use control and display screen. These features make the device more versatile with greater depth, better target separation, and audio functionality.
It is equipped with digital shield technology (DST) that minimizes the issues caused by power lines or cattle fences, enabling you to get closer to the target without the device becoming unstable and sounding off randomly.
Since the detector operates at 13 kHz frequency, it can find a wide range of targets in different ground conditions. You can even shift frequencies to accurately locate specific objects such as coins, gold, silver, and relics. In iron-infested regions, the detector eliminates unwanted targets with ease.
There is a function called FastGrab that activates automatic ground balancing. It measures the magnetic properties of the soil in order to cancel interference from naturally occurring minerals in the ground.
- Digital Shielding Technology suppresses electromagnetic radiation
- Double-filter discrimination mode for hunting in trashy regions
- Magnetic mineralization bar graph and readout
- Fully adjustable armrest
- Up to 40 hours of battery backup
- Steep learning curve
- Quite expensive
The LCD screen displays the electrical signature (target ID) of the detected item and provides continuous information on ground mineralization (which affects detection depth).
Other Greate Metal Detectors
OMMO metal detector comes with an IP68 waterproof search coil that can detect small coins and metal objects up to a depth of 8 inches, and larger objects up to 36 inches. It has three distinct modes to help you optimize your detecting process. Disc mode, for example, allows you to differentiate a specific type of metal from others.
While it works on dryland, beaches, and underwater, areas with excess metal waste and highly mineralized soil should be avoided.
11. Fisher GoldBug-DP
Fisher GoldBug-DP is specifically designed for finding small gold items. It has a sophisticated ground balancing system, an advanced discrimination control system, and separate control over signal gain and threshold.
Operating at a frequency of 19 kHz, this device can locate very small gold nuggets even in highly mineralized soils. It offers continuous ground condition readouts. Ground Phase value, for example, indicates the type of mineralization, and the Fe3O4 graphic indicates the amount of mineralization.
12. SUNPOW OT-MD03
OT-MD03 is an entry-level metal detector that allows searching in multiple terrains. It can accurately detect aluminum, gold, silver, and bronze. You can distinguish the type of material by their unique audio signals and ignore junk objects by configuring the DISC range to enhance the detection efficiency.
The machine comes with a 10-inch search coil, carry bag, folding shovel, and user manual. You will need to purchase 8x AA batteries separately. It is recommended to use alkaline batteries instead of carbon batteries.
13. Garrett Sea Hunter MK-II
Sea Hunter MK-II is an advanced pulse induction metal detector that allows you to explore treasures down to 200 feet. It has 22 frequencies to enable the best detection in harsh environments.

Frequently Asked Questions
Who invented metal detectors?
In 1874, French electrical engineer Gustave Trouvé invented a hand-held instrument for pinpointing and extracting metal objects (like bullets) from patients. Inspired by Trouvé, Alexander Graham Bell developed a metal detector through the use of an induction balance.
In 1925, Gerhard Fisher invented a more accurate metal detecting system based on radio direction-finding. These were the first advanced metal detectors to be sold commercially in 1931.
How does a metal detector work?
While different metal detectors work in different ways, their principle mechanism remains the same. The simplest form of a metal detector contains a coil of wire called a transmitter coil. When electricity flows through this coil, it creates a magnetic field all around it.
If you move the detector over an electrically conductive object, the object creates a magnetic field of its own. The magnetic field coming from the metal piece is detected by another coil of wire called the receiver coil.
This secondary coil sends a signal to the receiver circuit, which then makes a speaker buzz, alerting you that you have found something.
How deep a metal detector can detect?
A good quality machine can detect coin-sized objects 6 to 10 inches below the ground. In ideal conditions, it can find larger objects 14 to 16 inches below the ground. Some advanced detectors, operating at multiple frequencies, can go as deep as 60 inches. However, this depends on several factors, such as
- The size and shape of the target
- Metal composition (silver, copper, brass have higher electrical conductivity)
- Soil condition (mineralized soil can cause trouble)
- Detector’s sensitivity levels
What to considers before buying a metal detector?
Following are the questions you should ask yourself before making a purchase:
- What is it you want to find?
- Where will you use the detector?
- How often will you use the detector?
- How much experience do you have?
- How much money are you comfortable spending?
If you are a beginner, we will recommend you to go with a lightweight device that features automatic ground balancing, digital controls, multiple preset modes, and sensitivity adjustments so you can ignore trash items.
